Nutrient deficiency? Light burn? Why are they like this?

[queenweed]

Hey everyone!
So i have a few plants in veg with a constant sprinkler going, ph is typically between 5.4-5.6 and my ec ranges from 1.2-1.6 (after a few hours)... I came back this morning to check on them and noticed that some of the leaves are looking bizarre, really not sure what’s happening? i’m thinking it’s a nutrient deficiency however i am not sure as to what exactly it might be... anyone seen this before?? if so what’s happening

To me, it looks like maybe a copper deficiency, mainly because of the shiny look on the leaves, but it could be camera angle.
However, when you look at the leaves being cupped like they are, it might be something as simple as light burn. Any clue what the PAR is at canopy level?
Are the leaves that are doing this located directly under the light? I guess what I'd like to know is if leaves located with some shade, (maybe lower leaves) are doing the same thing? If so, you can rule out heat burn.
